Hi,
I have a problem when trying to follow information given in https://doc.ibexa.co/en/latest/content_management/rich_text/extend_online_editor/#configure-custom-data-attributes-and-classes

I already had the same kind of problem when ''embedimage'' and ''embedinline'' became ''embedImage'' and ''embedInline''.

There are many elements that don't work. And they are not simply ignored ; they "crash" the rich editor that don't show up anymore when I use these elements.

By instance, ''ul'', ''ol'', ''formatted'', ''heading'' prevent the editor from being shown. (paragraph, heading1 to heading6 work...)

And there are also a few elements the doc doesn't mention that work : ''listItem'', ''tableRow'', ''tableCell''..
 
And BTW, we'd like to be able to add custom classes or attributes to ''link''. If it vpould be added to the list, it would be fine
